A simple class that converts a image to a icon in c# without losing image color data, unlike System.Drawing.Icon; ico with png data requires Windows Vista or above
class PngIconConverter
{
/* input image with width = height is suggested to get the best result */
/* png support in icon was introduced in Windows Vista */
public static bool Convert(System.IO.Stream input_stream, System.IO.Stream output_stream, int size, bool keep_aspect_ratio = false)
{
System.Drawing.Bitmap input_bit = (System.Drawing.Bitmap)System.Drawing.Bitmap.FromStream(input_stream);
if (input_bit != null)
{
int width, height;

Common markup for Markdown and reStructuredText

Markdown and reStructuredText

GitHub supports several lightweight markup languages for documentation; the most popular ones (generally, not just at GitHub) are Markdown and reStructuredText. Markdown is sometimes considered easier to use, and is often preferred when the purpose is simply to generate HTML. On the other hand, reStructuredText is more extensible and powerful, with native support (not just embedded HTML) for tables, as well as things like automatic generation of tables of contents.
